Data Analysis and Visualization for YelpAs we all know, America is a country full of diversive culture. People from all over the world come here to work,study and live. Among different elements, food is one of the most interesting topics we want to discover since it is so deeply involved in our daily life. On a large scale, we are interested in the spatial distribution of number of restaurants in different states. Meanwhile, understanding restaurant’s price, rating, number of reviews and their kinds’ distribution will give us a rough idea about our own choice of food. As we went further in the discovery of restaurants, we expected we can find out connection between them by their kinds. All those questions drive us to Yelp, a popular website displaying restaurants information. The source of our data is Yelp’s API and its website and both our analysis and visualization are displayed in the following sections.
